Question

two sides of a triangle are of lengths 8.2 and 2.8cm . the length of the third side of the triangle is ?

Answer 1

Step-by-step explanation:

hypotenuse = 8.2 unit

side 2 = 2.8 unit

let's assume that the triangle is a right angled triangle

hence, (hypo)^2 = (side 1)^2+ (side 2)^2

8.2^2. = side 1 ^2 + 2.8^2

67.24. = side 1^2 + 7.84

side 1^2 = 67.24 - 7.84

side 1 ^2 = 59.4

side 1. = √59.4

side 1. = 7.70713955
